经阴道彩超检测置宫内金属节育器后子宫动脉及螺旋动脉血流动力学改变

摘要

Objective To forecast ahnormal uterine hemorrhage by transvaginal ultrasound detection of hemodynamic change of uterine artery and uterine spiral artery. Methods Pulse index( PI ),resistance inde ( RI )and systolic peak/diastolic peak( S/D )of uterine artery and uterine spiral artery was measured with transvaginal ultrasound on 82 women with stainless steel intrauterine device aged 25 to 46 years. Results PI and RI of uterine artery and uterine spiral artery in woman with ahnormal uterine hemorrhage was lower than that in normal woman. Conclusion Rish of abnormal uterine hemorrhage was increased in woman with lower PI and Rl of uterine artery and uterine spiral artery.%目的 应用阴道彩超检测置宫内金属节育器后子宫动脉及螺旋动脉血流动力学改变,预测放置宫内金属节育器后子宫异常出血情况.方法 82例要求放置宫内金属节育器避孕的随军妇女,年龄25 ～46岁.经阴道彩超测量其放置宫内金属节育器前后子宫动脉及螺旋动脉的搏动指数(PI)、阻力指数(RI)、收缩舒张比值(S/D).结果 放置宫内金属节育器后子宫动脉及螺旋动脉PI、S/D明显增加(P＜0.05).放置宫内金属节育器后伴有子宫异常出血妇女的子宫动脉、螺旋动脉PI、RI明显低于放置宫内金属节育器后月经正常的妇女(P＜0.05).结论 放置宫内金属节育器后子宫动脉及螺旋动脉PI、RI降低时,将增加子宫异常出血的风险.
